Designing a new bedroom for my autistic kids

How to prepare kids with autism to move home

We've just had new neighbours move in next door.  They are a young family and it's fair to say the move in took a long time.  We moved here just before Jane's first birthday.  In fact we were lucky to have sun on her birthday so we could have her party in the garden as the house was still in turmoil. Looking back the boys did really well with it all.   All kids can find change difficult, but with two autistic kids, what did we do to help them with this massive alteration to life as they knew it?
